IS THIS RIGHT <br> JUST ANSWER YES OR NO
Ivanshal [37]

Answer:

B

Step-by-step explanation:

x^3 + 2x^2 - 9x - 18 = x^2(x + 2) - 9(x + 2) = (x + 2)*(x^2 - 9)

(x + 2)/(x + 2)(x^2 - 9) = 1 / (x^2 - 9)

==============

1/(x^2 - 9) * (x^2 - 9)/(3x  + 1) = 1/(3x + 1)


Yes B is correct.

You are going to buy some cable television ads. You can get 20 spots for $1200 or 80 spots for $3200 what is the percentage disc
Lesechka [4]

Answer:

  33 1/3%

Step-by-step explanation:

When you buy 20 ads, the per-ad rate is

  $1200/20 = $60 . . . per ad

When you buy 80 ads, the per-ad rate is

  $3200/80 = $40 . . . per ad

The percentage change to the $60 price is ...

  ((new price) - (original price))/(original price) × 100%

  = ($40 -$60)/$60 × 100% = -20/60 × 100%

  = -1/3 × 100% = -33 1/3%

The higher volume purchase comes with a 33 1/3% discount.

PLEASE HELP ME!!!!!!!! ASAP
DedPeter [7]
Let's take these one at a time.
A
The A choice is that the y intercept of g(x) < y intercept of f(x). Remember, a y intercept occurs when x = 0
g(x) = 2 * sqrt(x) - 8
g(0) = 2*0 - 8
g(0) = - 8
=======
f(x) = - 4 when x = 0 (you just read it.) - 4 is greater than -8. That's a true statement. Think money. Would you rather be 4 dollars in debt or 8 dollars in debt? 
A: True <<<<<< answer for A.

B
y intercept  occurs when x = 0 The values of f(x) and g(x) have been found in part A.

Are they equal?

The y intercept of g(x) = g(0) = 2*sqrt(0) - 8 = - 8
The y intercept of f(x) = f(x)  = - 4 when x = 0 

Conclusion
They are not equal and B is not the answer.

C
The x intercept occurs when y = 0
g(x) = 0 
0 = 2*sqrt(x) - 8
8 = 2*sqrt(x)
4 = sqrt(x)
x = 16
======
When f(x) = 0, x = 16.

Conclusion
The x intercepts are both 16. This statement is true.
C: True <<<<<< answer.

D
If the condition is anything but equal, the statement is false. g(x) is not greater then f(x).

D <<<<<< False.
